Summary

AI summary

New hosted mode enables stateful orchestration without API keys, adds debate style options, context injection, and structured synthesis output.

Full changelog

What's New

Hosted Mode (No API Keys!)

New mode="hosted" where the MCP server acts as a stateful prompt orchestrator — it generates debate prompts but never calls model APIs. The host (Claude Code, Copilot, etc.) executes prompts using its own model access via sub-agents. Works with opus/sonnet/haiku in Claude Code. Same model can be used multiple times for diverse perspectives.

New brainstorm_collect tool for the host to submit model responses back to the server.

Debate Styles

New style parameter:

freeform (default) — open brainstorming
redteam — adversarial fault-finding, models find flaws, risks, and weaknesses
socratic — probing questions that expose assumptions and push for deeper understanding

Context Injection

New context parameter to ground debates in actual code snippets, PR diffs, error logs, or architecture docs. Models debate YOUR work, not abstract questions.

3-Bullet Synthesis Verdict

Upgraded synthesis output to structured format:

Recommendation — one clear, opinionated recommendation
Key Tradeoffs — 2-3 most important considerations
Strongest Disagreement — the sharpest unresolved tension (not watered down)

VS Code Copilot Support

.agent.md files for model-specific brainstorm agents
.vscode/mcp.json configuration for Copilot MCP integration
Tool asks user to choose API vs Hosted mode when not specified

Mode Selection UX

When mode is not provided, the tool returns a prompt asking the user to choose between API and Hosted mode — ensures the right flow every time.
